我无法找到原因，我确切地说这是一个带模块的maven项目，因此我将所有依赖项放在父模块pom文件中：

a1 = (ApplicantTO) applicantService.addDomain("DevOps", a1.getId());
// System.out.println(a1.getDomain());
System.out.println(applicantService.getAllApplicants());
};
}
}
我认为这个问题来自于pom，但我找不到。
答案 0 :(得分：0)
尝试升级springboot版本并添加这个依赖

<artifactId>spring-aop</artifactId>
<version>${spring.version}</version>
